3 dim orange lights in triangle formation moving at high speed before separating in different directions.

I went outside to walk the dogs and looked up to see 3 dim orange lights in a triangle formation moving rapidly in a westerly direction. Each light looked like this, II, and were on each corner.

I'm a Medevac pilot and estimate its altitude at approx 2000 ft above ground level and traveling at between 150 & 200 knots. I viewed it at a 45-50 degree angle, giving it an approx distance of 0.5 nm south of my house and heading westbound over downtown Hartwell.

Within 5-10 seconds of seeing it, it either rotated clockwise or the lights separated and went in different directions. After this it disappeared from view. The whole time it was completely silent.
